Check after every production day or at least once a day if the profiled
rail guides of the gripper base jaws are sufficiently lubricated.
Measures for preserving the gripper's function
The maintenance and lubrication intervals must be adapted to the
ambient and operating conditions.
Observe the following factors:
• Extreme operating temperatures
• The effects of condensation
• High vibration loading
• Use in a vacuum
• Very dynamic operation
• Permanent small stroke movements
• Influence of foreign substances (e.g. vapors or acids)
Preserving the gripper's function:
• Do not expose the gripper to drilling emulsion.
• Operate the gripper in an ambient temperature b5°C
and +55°C.
• Observe the bending radii when laying the cable. No torsional
movements must occur.
• Since it is a servo system motor, it can generate the indicated
forces only for a short term. These forces may overload the grip-
per and mechanically destroy it. Every overload leads to a de-
crease of the system's service life.
Do only operate the gripper within the scope of its technical data.
• Gripping force:
The repeat accuracy of the gripping force is ±15%. The breakaway
torque can vary significantly from gripper to gripper.
If an automatic gripper change shall be enabled, the breakaway
torque must be determined during an initialization of the superior
control.
For more information on the programming, see control manual.
